Fig. 18 is a section on the line I8-l8 of Fig. 17. from the phonograph. The front portion of the 55 magazine is similarly anchored to the rod 40.

For positioning the records, a plate 44 is secured to the bar 35, this plate being notched or slotted as clearly shown in Fig. 1 to form a series of prongs 45 which serve to receive records between them and to maintain such records in horizontally spaced relation. The front bar 31 is also provided with a plate 46 which is provided with a series of substantially V-shaped notches which are complementary to the pockets between the prongs 45 and serve to cooperate therewith to position the records R in edgewise, vertical position. The bar 36 is provided with an upwardly extending rib 41 which serves to support some of the weight of the records in cooperation with the notched plates 44 and 46.

The record transferring mechanism The record transferring mechanism includes a pair of jaws 48-48 which are of elongated arcuate form and adapted to clamp between them, a marginal portion of a record as is clearly shown in Figs. 5 and 12. The jaws 48 may be conveniently provided with a felt or like lining 49 for preventing injury to the engaged portions of the records.

Each jaw 48 is formed with a pair of relatively spaced bosses 50, in which laterally extending pins 5| are fixedly mounted. The free ends of the pins 5| are connected by a strap 52 (see Fig. 9).

The pins 5| of the jaws are slidably received in suitably apertured bosses 53 which are formed integral with a jaw mounting element 54 (see Fig. 12). The jaw mounting 54 includes a cylindrical stem portion 55 and a head portion including relatively spaced arm portions 56-56 with which the bosses 53 are integrally formed. The head portion of the jaw mounting also includes opposite side flange elements 51, each of which is provided with an angularly disposed notch 58 in its front outer corner (Figs. 9 and 10).

The arm portions 56-56 of the jaw mount are respectively provided with suitably apertured bosses 59 which slidably receive pins 60-66 which are secured to the strap or cross plate 52. Springs 6| are disposed around the pins 60 between the respective cross plates 52 and bosses 59, and serve to normally urge the record gripping jaws 48 to move outwardly, that is to say, to separate from each other.

The cylindrical stem portion 55 of the jaw mount is rotatably and axially, slidably mounted in a suitably apertured boss 62 which is formed integral with a jaw lcarrier 63. The carrier 63 is of inverted, substantially U-shaped form and includes side arm portions 64-64 which are joined by a cross bar 65. The side arm portions of the carrier are suitably apertured to rotatably t on a cam shaft 66 so that the jaw carrier 63 and the parts mounted thereon may be swung or pivoted around the axis of the cam shaft 66.

The cylindrical stem portion 55 of the jaw mount is bored out axially to slidably receive a stem or pin 61 which is provided at its outer end with a head 68 which fits between the arm portions 56 of the jaw mount. The head 68 is provided with a substantially v-shaped notch, whereby inwardly and downwardly inclined cam walls 69 are formed. The cam walls 69 are designed to cooperate with similar cam walls 1|) formed on the portions of the jaw members 48 which extend into the V-shaped notch of the head 68. The opposite or inner end of the stem or pin 61 is provided with a collar 1I which is slidably received in a counterbore 12 in the inner end of the stem 55 of the jaw mount. A spring 13 interposed between the collar 1| and the bottom of the counterbore 12 serves to normally urge the cam headed stem 61 to move inwardly so as to permit the springs 6| to separate the jaws.

The record gripping jaws 48 are swung from an upwardly extending position in operative relation to records in the magazine as shown in Fig. 5, to a substantially horizontal position in operative relation to a record on the turntable substantially as shown in Fig. 13, through the agency of a connection between the cam shaft' 66 and the jawv carrier 63. The cam shaft 66 is rotated by means which will presently be described. The connection between the cam shaft 66 and jaw carrier 63 includes a disc 14 which is secured on the cam shaft 66 in nxed relation thereto and a pin 15 which is slidably mounted in a portion of the jaw carrier in alignment with the disc 14; As best shown in Fig. 12, the jaw carrier 63 is provided with a boss 16 which is bored out to receive the pin 15. The boss 16 is also counterbored as indicated at 11 so as to receive a collar 18 carried by the pin 15 adjacent its inner end.

A spring 19 is interposted between the collar 18 and the bottom of the counterbore 11 and serves to urge the pin 15 to move inwardly against the periphery of the disc 14. 'I'he latter is notched as indicated at to receive the inner end of the pin 15 as shown in Fig. 12 so that there is a semipositive driving connection between the cam shaft 66 and the jaw carrier.

'I'he cam shaft 66, during normal operation of the record transferring mechanism rotates slightly less than one full revolution forward and the same amount backward. However, the actual swinging movement imparted to the jaw carrier and record clamping jaws is considerably less than the full extent of rotation of the shaft 66, it being only necessary to swing the jaw carrier from its upwardly and rearwardly extending position as shown in Fig. 5 to horizontal forwardly extending position as shown in Fig. 13 (approximately 130 degrees). Rearward swinging movement of the jaw carrier, i. e. from its horizontal forwardly extending position to its rearwardly and upwardly extending position as shown in Fig. 5 is limited by engagement of the boss portion 16 of the jaw carrier with a stop portion 8| 14 continues its rearward rotation and forces the pin 15 to move outwardly, whereupon its outer end enters an aperture 82 which is provided in a flange or lip portion 83 which is formed integral with the stop 8l and frame 21 (see Figs. 5 and 14). When the pin- 15 enters the opening 82, the jaw carrier 63 is locked in its proper operative relation to the record magazine.

Upon forward rotation of the shaft 66, the pin 15 will reenter the notch 80 in the disc 14, whereupon the jaw carrier will be swung in a forward direction until its operative horizontal position, as illustrated in Figs. 9, 13 and 14, is reached. Forward swinging movement of the jaw carrier is stopped by engagement of a bar element 84 which extends between and is formed integral with the outer ends of the-respective pairs of bosses 53, with a stop bar 85 which extends between and is formed integral with oppositely disposed frame portions f1. when the horizontal position is reached by the jaws and jaw carrier, such engagement prevents the disc 14 from further rotating the jaws with the result that the pin 15 is again forced outwardly and caused to enter an aperture 86 (Fig. 14) provided in an upwardly extending fiange-like portion 81 of the frame 21. By this means, the jaws are locked in operative relation to the turntable and a record thereon, while the cam shaft 66 is permitted to continue its rotation to effect further operations.

As shown in Fig. 2, the record gripping jaws 48 initially assume a position adjacent the periphery but outside the area of the records R in the record magazine. When the magazine has been adjusted to locate the desired record opposite the gripping jaws, the jaws are moved inwardly so as to overlap the adjacent marginal portion of the record as indicated in Fig. 5. Such inward movement of the jaws is effected by means of a pair of cams 83 which may be formed integral with a third cam 89, the entire cam unit being xedly mounted on the shaft 55. The cams 88 engage a collar 89a which is rotatably mounted on the inner end of the sleeve 55. The collar 89a bears against a collar 90 which is xedly secured to the stem 55, anti-friction bearings being interposed between the collars 89a and 90 as shown. A spring 9| interposed between the collar 90 and the cross arm portion 95 of the carrier 63 serves to normally urge the jaw mount to move inwardly so as to maintain the collar 89a in engagement with the cams 88. In Fig. 12, the jaw mount is shown in its outermost position, wherein a record R enters between the jaws 48, this position corresponding to that shown in Fig. 5. The cams 88 are properly shaped to permit the spring 9| t0 retract the jaws at the proper times.

For moving the jaws towards each other against the pressure of the springs 6|, the cam 89 acts against the inner end of the stem 51 to force the cam head thereof to act on the cam surfaces 10 of the respective jaws in a manner readily understood by inspection of Fig. 12. The cam 89 is, of course, shaped so as to allow the cam headed pin 61 to be retracted by the spring 13 at the proper times to free the record.

Turning movement of the record and jaws 48 about the axis of the pin 61 and stem 55 is eiected as an incident to their movement from the magazine to the turntable so as to deliver the record in horizontal position to the turntable. The means for effecting such turning movement includes a jaw turning device 92 which is in the form of a U-shaped device (see Fig. 9) having the upper ends of its respective arms provided with pins or studs 93 and 911 respectively. The U-shaped member 92 is provided with a boss 95 in `its bottom which is suitably bored out and mounted on the drive shaft 29. As best shown in Fig. 13, a bushing 99 is seated in a portion of the frame 21 so as to support the turning device 92 for pivotal movement about the axis of the shaft 29. Wear on the U-shaped device by reason of constant rotation of the shaft 29 is thus eliminated andv free running of the shaft 29 is not hampered.

A laterally extending boss 91 is formed integral with the boss Q5 of the U-shaped member and a rod 98 is mounted in and projects from the boss 91 as clearly shown in Figs. 9 and 19. The free end of the rod 99 is provided with a spherical formation 99 which fits in an opening in the free end of a lever |99 which is pivo as indicated at I! on a bracket lug formed integral with the frame 21 (see Fig. 2). Intermediate its ends, the

arm |00 is provided with a pin or stud |02 which fits in a generally circular zig-zag cam-way |03 formed in a disc |04. The disc |04 is supported for rotation by a shaft |05 which is rotatably supported in suitable bearing brackets such as indicated at IBS-A06, the latter being conveniently formed integral with the frame 21. The shaft |95 and disc |04 are rotated step by step by means which will presently appear. the disc |64 serves, through the cam-Way |03 and lever |00 to effect rocking of the jaw turning device` 92 about the axis of the shaft 29 so as' to cause one of the studs 93 or 94 to be aligned with the open end of one of the notches 58-50, while the other stud 03 or 94 is moved out of the path of travel of the notches 59-58. By reference to Fig. 10, it will be seen that the stud 93 is shown in the path of travel of the adjacent notch 58 while the stud 94 is outY of the path of travel .of its adjacent notch 58.

Upon downward swinging movement of the jaw carrier, the flange elements 51-51 are guided between guide plates |01|01 which are formed integral or suitably mounted on the frame and provided with suitable inwardly facing guide surfaces |08. By reason of the straight portions |09 of the ange elements 51-51, the jaws are caused, during the initial portion of their downward movement, to hold the record in substantially vertical position, thereby effecting removal of the record from the magazine before any material extent of turning movement is imparted to the record. When the jaws and record reach a predetermined lposition near the horizontal, one of the notches 58 engages whichever stud 93 or 94 is in operative position (93 in Figs. 9 and 10), whereby the stud becomes a pivot about which the jaw mount is turned. Of course, the jaw mount also turns about the axis of its stem 55 which travels through a xed path of travel. The elongated slots 58 serve, however, to permit relative sliding movement between the stud 93 and flange which it engages, While also constituting a pivot.

When a record has been played, means which will presently be described causes the shaft 66 and inward carrying jaws to travel in the reverse direction to return the record to the magazine. During such returning movement, the stud last engaged by the ange 51 is again engaged to return the jaws from horizontal to vertical position. The rear corner portions of the flanges 51 are rounded ol as indicated at I0 to facilitate the turning movement just described. It will be seen that by bringing the studs 93 and 94 successively into operative position, the record carrying jaws will be caused to turn in opposite Such rotation of directions so that both sides of a double faced record may be successively played.

Cam shaft driving means The cam shaft 66 is driven alternately in opposite directions by means of a driving connection from the continuously driven shaft 29. These driving connections include the following mechanism:-A short countershaft (see Figs. 13 and 19) is mounted'for rotation in a. suitable boss I|2 formed integral with the frame 21 and this countershaft is continuously driven by means of a gear connection with the main shaft 29,the said gear connection being designated ||3` in its entirety. The opposite end of the countershaft ||3 is provided with a bevel pinion gear H4. The bevel pinion gear I4 is adapted to mesh alternately with bevel gears I |5 and I6 which are xedly mounted on projecting end portions of an elongated pinion gear ||1. The gear assembly ||5, ||6 and ||1 constitutes a unit which is freely rotatable on a shaft ||8 which extends transversely of the main shaft 29 and is journalled in suitable frame lugs ||9 (see Figs. 7 and 19). The composite gear unit just mentioned is maintained against endwise movement on the shaft ||8 by means of collars |20 which are pinned to the shaft ||8. The pinion gear I |1 meshes with a gear |2| which -is suitably secured to the cam shaft 66 so as to impart rotation thereto.

For alternating the direction of rotation of the gears ||1 and |2| and of the cam shaft 66, the shaft ||8 is caused to move endwise to alternately effect intermeshing of the bevel gears ||5 and ||6 with the bevel pinion gear I |4. Such endwise movement is imparted to the shaft through a spring device which is actuated by means of a connection with the shaft 66.

The spring device just referred to includes a spring |22 which is positioned around the shaft ||8 and interposed between a pair of thimbles |23 and |24 which are also mounted on the shaft ||8, the thimble |24 being pinned thereto as clearly indicated in Fig. 7. Each of the thimbles has an annular flange |25 at its inner end. A cage or barrel- |26 has an integrally formed, inwardly extending flange |21 at one end adapted to cooperate with the flange |25 of the adjacent thimble |24, and a removable head |28 at the other end of the barrel |26 provides an inwardly extending flange |29 which is adapted to engage the annular flange |25 of the adjacent thimble |23. It will be seen that the spring. |22 normally tends to force the thimbles |23 and |24 apart, such spreading thereof being limited by engagement of their respective anges |25 with the respective flanges |29 and |21 of the barrel |26.

A cam disc |30 is secured to the shaft 66 so as to rotate therewith and it is provided with a pair of laterally extending, circumferentially spaced pins |3| and |32 respectively, which are adapted to engage an upstanding portion |33 of a bell crank |34. The bell crank |34 is pivoted as indicated at |35 on a portion of the frame and its other arm is provided with a depending pin |36 which fits between a pair of pins |31|31 which project laterally from the barrel 26 (see Figs. 5, 7, 19 and 20).

When the record transferring jaws 48 are in initial position as shown in Fig. 2, the shaft ||8 is in its extreme left hand position (not illustrated). At such time, the spring barrel |26 is also in its extreme left-hand position, and the upstanding member |33 of the bell crank |34 is in position to be engaged bythe pin |32 upon completion of the forward rotation of the cam shaft 66. When the pin |32 engages the upstanding part |33 of the bell crank |34, the latter is swung so as to move the barrel |26 towards the right, substantially to the position shown in Figs. 19 and 20. When the cylinder |26 moves in that manner, the spring |22 cona portion of the frame or one of the guideways |40 and a part of the bar |39 urges the bar |39 to move forwardly. Such movement is normally prevented by a pawl |42 which is pivoted at one end' as indicated at |43 on the frame, the other end of the pawl being shaped to enter a notch |44 in the bar |39. A leaf spring |45 normally holds the pawl |42 in engagement with the bar |39.

During forward movement of the record transferring device, the shaft ||8 occupies its extremel left hand position wherein the gears ||4 and ||6 are in engagement for transmitting proper rotation to the cam shaft 66. When the record is delivered to the turntable and released from the clamping jaws 48, the pin |32 on the disc |30 effects the above described compression of the spring |22 to thereby effect movement of the shaft ||8 towards the right. Such right hand movement, as above stated, is limited by engagement with the stop 38 which is so arranged as to stop the shaft I |8 at a point to maintain both of the bevel gears ||5 and ||6 out of engagement with the pinion gear |4,- i. e. in a neutral position, whereby rotation of the cam shaft 66 ceases.

When the record on the turntable is completely played, an electro magnet |46 is energized and acts on a soft iron extension |41 of the pawl |42 to disengage the pawl from the bar |39. Thereupon the spring |4| causes the bar and stop |38 to move forwardly to substantially the position indicated in Fig. 20. Upon such movement, the shaft ||8 is permitted to move further to the right under the stored up power of the spring |22, thereby to effect intermeshing of the bevel gears ||5 and 4. The pinion gear ||1 is thus driven in the reverse direction to thereby effect reverse rotation of the cam shaft 66 and return movement of the record carrying jaws.

Incidentally, it might be noted that an insulating material element 222, carried by the bar |39 serves to separate resilient electric contact members 223 and 224 when the bar |39 is moved forwardly by the spring |4|. The contact elements 223 and 224 constitute a switch which is incorporated in the electric circuit of the magnet |46, and it will be observed that the circuit to the magnet is broken immediately after the pawl |42 is withdrawn from engagement with the bar |39.

The contacts 223 and 224 are, of course, mounted on a suitable insulating material element which is carried by a conveniently accessible portion of the frame.

It is desirable to provide means for locking the gears ||5 and ||6 in operative engagement with the driving gear I4, and for this purpose, the shaft I8 is provided with a cylinder 48 which is provided with annular flanges |49 and |50 at its opposite ends. The cylinder |48 is fixedly mounted on the shaft ||8. A pair of locking dogs |5| and |52 of bell crank formation are disposed in opposite arrangement and pivoted on a common pivot |53 on a part of the frame 21 (see Figs. 1'1, 19 and 20). The locking dogs |5| and Y|52 are connected by a -spring |54,which tends to rock them into engagement with the surface of the cylinder 48. When the shaft ||8 is in its lefthand position, the dog |5| engages the shoulder or ange |49 to lock the shaft in such position, and when the shaft is in its extreme right-hand position as illustrated in Fig. 20, the dog |52 engages the shoulder |50 to lock the shaft in such position. When the cylinder |26 is moved to the right as above explained, the dog |5| is released from the shoulder |49 by means of a finger |55 which is carried by the cylinder and provided with a laterally extending end portion |56 which extends upwardly between the spring connected arms of the bell crank dogs |5| and' |52. As shown in Fig. I9, the nger portion I 56 engages. one arm of the dog I 5I to rock the dog out of engagement with the stop ange |49. When the shaft ||8 is permitted to move to its extreme right-hand position as shown in Fig. 20, the dog |52 is caused, by the spring |53, to drop behind the stop shoulder |50. Upon movement of the cylinder towards the left as will hereinafter be described, the finger portion |56 engages the arm of the bell crank dog |52 to disengage it from the shoulder |50 to thereby again permit the shaft |I8 to move under the influence of the spring |22. It will be observed that because of the play between the spring connected arms of the bell crank dogs, the spring |22 is permitted to be compressed a considerable extent before any movement is imparted to the shaft H8. Hence, the shaft |I8 is caused to move with a quick or snap action.

When the cam shaft 66 is rotated rearwardly to effect transferring of a record from the turntable to the magazine, the movements imparted to the record gripping mechanism are, of course, in the reverse order to those explained in connection with the transfer of a record from the Cil magazine to the turntable. The pin |3I, carried by the disc |30, then acts, near the end of the rearward rotation of the shaft66, against the upstanding portion |33 of the ball crank |34 to effect movement of the spring barrel |26 towards the left as above mentioned. Such movement imparted to the spring barrel |26 has the effect of moving the shaft II8 towards the left upon cornpletion of the record return operation, and serves to effect re-engagement of the gears ||6 and ||4 preparatory to a new record transferring operation. Upon reengagement of the gears ||4 and II5, the record transfer mechanism operates to transfer the same record back to the turntable, but turning it in the opposite direction to play the other face, or to transfer a new record to the turntable.

Means for actuating coin control mechanism Automatic phonographs of the type herein described are often equipped with coin control devices which require the insertion of one coin for each record to be played. When the phonograph is so equipped, I prefer to provide means for stopping the operation of the phonograph just prior to shifting of the shaft IIIi4 and gears |I5 and ||6 relative to the driving gear II4. In the present instance, a cam |51 is mounted on the cam shaft 66 for actuating a lever |58 which is pivoted as indicated at |59 on a part of the frame. 'I'he free end of the lever |58 is connected to a coin operated electric switch in such a manner that when the lever is swung downwardly, the coin controlled switch is actuated to break the electric circuit to the driving motor 28. The lever |58 is actuated through an arm '|60 which is pivoted near its lower end to an intermediate portion of the arm |58, the free end of the said arm |60 being acted upon by the cam |51 (see Fig. 17) A spring |6| normally tends to maintain the arm |60 in upwardly extending position and against a stop |62 which is formed integral with the arm |58.

In Fig. 17, the parts are shown in the positions which they occupy when the record transfer dethe said arm |60 will be imparted to the lever |58 to thereby actuate the electric switch to break the motor circuit. Inasmuch as the shaft 66 and cam |51 will turn just slightly less than one complete revolution, it will be seen that the high point of the cam |51 will pass the end of the arm |60 whereupon a suitable spring, which may conveniently be a part of the coin control mechanism (not shown), will restore the lever |58 and arm |60 to its initial position substantially as shown in Fig. 17. When the electric circuit to the motor is again completed by the deposition of a proper coin, the cam shaft-66 and cam |51 will be caused to rotate in the reverse direction. Upon such rotation, the cam acts to swing the arm |60 rearwardly about its pivotal mounting on the lever |58 against the tension of the spring 6| and without effecting movement of the switch controlling arm |58.

I prefer to time the ca'm |51 and spring barrel actuating pin I 3| so that the motor circuit will be broken just prior to actuation of the barrel |26 and shifting of the gears I I5 and I I6 relative to the driving gear I I4. Hence, it will be understood that the mechanism comes to rest Record magazine shifting mechanism 'Ihe record magazine is shiftedl by means of a cam |63 which is mounted on the shaft |05 for rotation thereon in unison with the disc |04. The cam |63 is provided with a plurality of seats |64 which are progressively stepped outwardly from the axis of rotation of the cam, the number of seats corresponding to the number of records to be handled by the record magazine. As, clearly shwn in Fig. 2, there is a radially extending edge |65 which connects the inner and outer, or lowest and highest seats of the cam |63.

The cam |63 acts against a roller |66 which is carried by the connecting pivot pin |61 of a pair of arms |68 and |69. The arm |68 is mounted on a fixed pivot as indicated at |10. The arm |69 is pivotally connected at |1I to the end of one arm of a bell crank |12 which is pivoted as indicated at |13 (Fig. 1) on a part of the frame 21. The free end of the other arm of the bell crank |12 is provided with an upwardly projecting pin |14 which enters a guideway |15 formed in a part of the magazine frame.

When the cam |63 acts on the roller I61to force it outwardly from the center of the shaft |05, the bell crank |12 is caused to swing about its pivot |13 (in a counterclockwise direction in Fig. 1) to thereby shift the record magazine one step to the left as viewed in Fig. '7 (towards the bottom of Fig. 1).

'I'he shaft |05 andcam devices carried thereby are rotated step by step by means of a pawl and ratchet arrangement. The ratchet is designated |16 and is secured to the disc |04 and cam |65 so that said parts constitute a unit adapted to rotate as such on the shaft |05. A pawl |11 is pivoted on the free end of an arm |18, the other end of which arm is pivotally mounted as indicated at |19 on an upstanding lug part of the frame 21. Intermediate its ends, the arm |18 is provided with a laterally projecting pin which is adapted to be engaged by a cam projection |8I formed on the periphery of the disc |30.

By reference to Fig. 11, it will be seen that when the disc |30 makes its next revolution (in a counterclockwise direction), the cam I8| will engage the pin |80 to effect upward swinging movement .of the arm |18, whereby the pawl I1.1 imparts one step of clockwise turning movement to the ratchet |16, and the cam disc and cam |04 and |63 respectively. At the end of the counterclockwise turning movement of the disc |30, the cam |8| will be disposed under the pin |80 so that upon starting forward or clockwise turning movement, the pin |80 will be permitted to ride down the surface of the cam |8| until it again rests on the periphery of the disc |30, as shown in Fig. 17.

lnasmuch as the cam shaft 66 makes one forward and one rearward rotation for each record played, it will be understood that one step of rotation is imparted to the cam disc |04 and cam |63 for each record played. Inasmuch as the mechanism is operative to play both sides of each record successively, it is, of course, desired to shift the record magazine only once for every other selection played. To effect such .shifting of the magazine, the camsteps |64 of the cam |63 are elongated so that one step of rotation of the cam will merely change the position of the roller |66 on the same seat of the cam, while the next step of rotation of the cam will eiect outward movement of the roller |66 and consequent shifting of the magazine. 1

When the entire series of records in the magazine has been played, the roller |66 is permitted to ride off theend of the highest cam seat |64, down the radial connecting edge |65 to the lowest cam seat |64. Such movement permits a spring |82 (Fig. l) connected between the upstanding frame part 4| and a point on the magazine frame to retract the magazine from its advanced position at the left-hand side of the machine to its fully retracted position at the righthand side of the machine. Such movement of the magazine is, of course, transferred through the bell crank |12 to the arms |69 and |68 so as to cause the cam roller |66 to ride down the radial cam edge |65. A suitable dash-pot arrangement |83 may be provided for preventing jars and shocks incident to return movement of the magazine.

Manua record selection .rotatably but axially slidably mounted on the said shaft. A spring |85 (Fig. 9) normally urges 4latter against its stop pin 2I3.

the said ratchet |84 to move towards a cooperating ratchet formation |86 on the adiacent face of the ratchet |16. During the playing of a record and during the ordinary operation of the phonograph, the ratchet |84 is maintained out of engagement with the ratchet element |86 by means of a cam controlled lever |81 which is pivoted intermediate its ends as indicated at |88 on a stud |89 which is carried by the frame or guide part |06 (see Figs. 9 and 17).

The upper end of the lever |81 is properly shaped to iit in a groove I 90 formed in the ratchet element |84 so that the lever |81 is capable of shifting the said ratchet against the pressure of the spring |85. The lower end of the lever |81 is provided with a laterally extending portion I9I (see Fig. 17) which extends into overlapping engagement with a side portion of the disc |30. 'I'he said side portion of the disc |30 is provided with a recess |92 into which the lever portion I9I may enter at such times as the electric circuit to the motor is broken and the mechanism rendered stationary. When the said lever portion enters the notch |92, the spring |85 is, of course, permitted to slide the ratchet |84 into engagement with the ratchet element |86, whereupon rotation of the shaft |05 will be Yoperative to rotate the cam disc I 04 and magazine feed cam |63. The ratchet arrangement |84 and |86 is, of course, such that it is capable of rotating the cam disc and cam only in the forward direction. For facilitating manual turning of the shaft |05, itis provided with a gear |93 which is engaged by a pinion gear |94 carried by the shaft |95 of a hand knob |96. By reason of the described gear connection |93 and |94 between the hand knob |96 and shaft 05, manual turning of the shaft |05 is rendered comparatively easy.

Because of the fact that it is comparatively easy to turn the cam |63 for manually selecting the record to be played, there is a tendency to turn the cam so fast that record No. 1 will be unintentionally passed by. This tendency, in the case of No. 1 record is augmented by the fact that the cam roller |66 rides off the high cam seat |64 and travels inwardly to the lowest cam seat |64. When the cam roller |66 leaves the high cam seat |64, the latter is freed from the resistance incident to the pressure applied thereto by the magazine returning spring |82.

In order to temporarily lock the cam |63 against such overturning movement, the following locking mechanism is providedz A lever 2|| is pivoted at one end as indicated at 2|2 on the inside face of the cam |63. A stop pin 2|3' also carried by the cam |63 is provided for limiting outward swinging movement of the lever 2| I. The free end of the lever is provided with a seat portion 2|4 which coincides with a portion of one of the seats 209 and an extension 2|5. A small bell crank 2I6 is pivoted as indi cated at 2|1 on the inside face of the cam |63 and is so arranged that its short arm 2 I8 engages the adiacent edge of the lever 2I| to hold the A spring 2I9 connected between the bell crank arm 2 I8 and a portion of the cam |63 serves to normally urge the bell crank into the position illustrated in Fig. 2 wherein the lever 2|I is held against the stop pin 2|3. The other arm 220 of the bell crank 2|6 is elongated and projects beyond the radial edge |65 of the cam |63.

When the cam |63 and disc |04 are rotated to cause the cam roller |66 to leave the high cam seat |64, the roller 208 enters the seat 209 with which the stop lever 2|| is associated. In the event that the cam and disc are rotated so fast that the cam roller 208 enters the new seat 209 before the cam follower |66 engages the lowermost seat |64, further rotation of the cam and disc will be prevented by the projecting end portion 2|5 of the stop lever 2| l. The arm 20| is limited in its rocking movement by a stop 22| so that the cam roller 208 can not swing outwardly enough to pass the projecting end 2|5 of the stop lever.

When the cam follower` |66 actually lreaches its lower-most cam seat |64, it engages the arm 220 of the bell crank 2|6 and swings the same on its pivot against the tension ofthe spring 2 I9 to thereby unlock the lever 2|| to permit the same to swing inwardly on its pivot 2|2. When the stop arm is thus permitted to swing inwardly, the projecting end portion 2|5 will be retracted so as to permit the disc |04 to be further rotated to manually select the desired record.

In addition to preventing overturning of the cams in the manual selection of a record to be played, the described locking mechanism serves to prevent similar overturning of the cams during the automatic operation of the mechanism, and thereby insures playing of the first selection after completion of the last selection. Also, in the event that the magazine resists return movement to such an extent that the rst record is not properly aligned with the record gripping jaws, the member 20| will be held in displaced position in which the electric motor circuit is broken so that the operation of the magazine cannot take place until the parts are properly adjusted.

M otor circuit control For preventing the establishment or completion of an electric circuit to the motor during such time as the ratchet |84 is in engagement with the ratchet formation |88, a 'switch device incorporated in the motor circuit is associated with the lever |81. This switch device includes (see Figs. 1, 1'1 and 18), a reversed L-shaped contact element |91 which is carried by a block |98 of insulating material secured to the lower end portion of the lever |81. The contact 91 also includes a leg |99 to which a conductor 200 constituting part of the motor circuit may be connected. An arm 20| is pivoted intermediate its ends as indicated at 202 on a conveniently accessible portion of the frame 21. The inner free end of the arm or lever 20| is provided with an enlargement which is bored out to receive an insulating material tube 203, within which is slidably mounted an electric contact element 204'. The contact element 204 is normally urged into contact with the reversed L- 'shaped terminal |91 by means of a spring 205 which is interposed between the rear end of the contact element 204 and a terminal 206. The terminal 206 has connected to it a conductor 201 which also forms a part of vthe motor circuit. The conductor 201 enters the tubular insulating element 203 through-suitable apertures in the end of the arm v20| and the insulating tube, and is suitably connected to the terminal element 206. The connection between the conductor 201 and terminal 206 may conveniently be effected by pulling the conductor through the opening in the insulating tube 203 and attaching it to the terminal 206 and then pulling the conductor and attached terminal rearwardly through the tube. Other arrangements for facilitating connection of these elements may also be provided.

'I'he other end of the lever 20| is provided with a laterally projecting roller 208 which is adapted to seat in notches such as 209 in the periphery of the disc |04. A spring 2|0 stretched between the lever 20| and a suitable anchorage carried by the frame 21 serves to normally urge the lever 29| to occupyl its operative position whereon the roller 208 is seated in one of the natches 289.

When the ratchet |84 is in engagement with the ratchet |86 and the mechanism thus rendered manually adjustable, the arm |81 is swung to approximately vertical position as indicated in Fig. 18 (compare Figs. 9 and 18) wherein the contact element 204' is in engagement with the offset lower leg portion of the reversed contact element |91. When the disc |04 is caused to turn through the provision for manual record selection, the roller 208 is forced out of one of the notches 209 to thereby `rock the lever-20| on its pivot 202 against the tension of the spring 2| 0. When the lever is so rocked, the contact element .204 rides off of the lower offset portion of the contact element |91 and merely engages the face of the insulating block |98, thereby breaking the' motor circuit so that even though a coin were deposited to thereby complete the circuit so far as the coin control switch is concerned, the circuit would nevertheless remain broken. However, the contact element 204 would again be permitted to engage the offset portion of the contact |91 when the disc |04 is rotated sufficiently topermit the roller 208 to enter another notch 209. 'I'hereupon the motor circuit would be completed and the mechanism lsei; into operation. The recess |92 in the disc |30 is very short and almost immediately upon rotation of the cam shaft 66 and the disc |30, the ratchet clutch controlling lever |89 would be forced out of the rec-ess and the ratchet clutch disengaged to thereby prevent further manual adjustment of the mechanism.

ASound reproducer or pick-up mechanism A n electric pick-up device is illustrated although it is, of course, to be understood that an ordinary mechanical producer may be substituted. The pick-up herein disclosed includes the head element 225 which carries a suitable needle or stylus 226 for engaging the sound groove of a record. The head 225 is mounted at one end of an arm 221, the other end of the arm being pivoted as indicated at 228 for vertical swinging movement. 'I'he pivot 228 is mounted in a cradle 229 which has a vertically extending stem or post portion 230 which is rotatably mounted in a suitable bearing in a lever 23|. The arm 221 and stem 230 may be tubular so as to receive an electric conductor which is connected at one end to a contact element 232 mounted in the arm 221. Other conductors connected with the pickup head 225 may extend through the hollow arm 221 and stem 230 to their connections with electrical' reproducing and amplifying mechanism (not shown). sulated from the arm 221 by means of a suitable insulating bushing 233, and it is provided with an adjustable screw 234 and a swinging contact element 235. The purpose of these parts will presently be explained.

The lever 23| is pivoted near one end for vertical swinging movement on a pivot pin 236 which is mounted in a boss 231 formed integral with the adjacent guide element |01. The free end of the lever 23| is provided with a supporting shelflike portion 238 which/,is adapted to engage a,

The contact element 232 is inlug 239 which depends from the pick-up arm 221. The supporting shelf 238 is preferably provided with a groove 240 for receiving a tongue portion 24| of the pick-up arm when the arm is swung to upwardly extending position to thereby hold the arm in predetermined, outwardly disposed position.

The pivoted end of the lever 23| is also provided with a rearwardly extending leg 242Y which is provided with a cam roller 243 adapted to engage the inside of a cam flange 244. The cam 244 extends laterally from a cam head 245 which is mounted on the cam shaft 66 for rotation therewith. Another cam 246, mounted on the cam shaft 66 within the cam ange 244, is provided for acting on the ball end 241 of an arm 248 which is secured to the lower end of the post 230 which projects through the lever 23|. The cam 246 may conveniently be formed integral with the cam head 245 and cam flange 244, if desired (see Fig. 8).

The operation of the pick-up arm is substantially as follows:-

When the mechanism is in its initial position, the pick-up arm is disposed in 'an upwardly extending position substantially as shown in Figs. 5 and 21. The cam ilange 244 serves to hold the arm in such upward position by reason of engagement of the cam flange with the roller 243. The arm 221 is also in an outwardly disposed position by reason of the action of the cam 246 on the ball end of the lever 248.

When the mechanism is operated to place a record on the turntable, the cam shaft 66 and cam elements 244 and 246 rotate in a clockwise direction as viewed in Figs. 5 and 21. When the record is far enough advanced towards the turntable, the cam 244 permits the lever 23| and arm 221 to swing downwardly by gravity until the stylus 226 engages the record just placed on the turntable. By reason of the pivotal mounting 228 of the arm 221, slight movement of the lever 23| is permitted after the stylus 226 engages the record. Such additional movement of the lever serves to disengage the tongue and groove 24| and 240 to permit free movement of the pick-up across the face of the record. Inasmuch as the pick-up arm 221 is initially in its outermost position as shown in Fig. 1, the stylus will normally engage the outermost portion of the sound groove of the record. To insure engagement of the stylus with the playing groove of the record, the axis of the turntable may be canted slightly so as to cause tl' a turntable and the record thereon o slope slightly downwardly from the side on which the pick-up initially engages the record. The pick-up is then caused to engage the smooth marginal portion of the record, and the slope of the record causes the pick-up to travel inwardly across said smooth portion until the starting end of the sound groove is engaged.

The cam 246 is inactive during the movement of the arm 221 to playing position although it does, of course, rotate in `unison with the cam 244.

When the playing of the record is completed, the set screw 234 of the contact element 232 engages a contact member 249 (Fig. 9) which is connected through the agency of a spring 250 to a terminal 25| to which a conductor 252 is connected. The conductor 252 constitutes part of the circuit to the electro-magnet |46 which, when energized, causes the cam shaft 66 to rotate in the reverse direction to return the playing record to the magazine.

The contact element 249 is mounted on an insulating material bracket element 258 which is mounted on the frame 21. The element 249 is yieldingly maintained by the spring 250 in its upright position wherein it is adapted to be engaged by the contact screw 234. A stop pin 259 serves to limit swinging movement of the element 249 under the influence of the spring 250.

The swinging element 235 is adapted to engage the serrated upper edge of a member 260 which is pivoted as indicated at 26| on the insulating material member 258. maintains the member 260 in predetermined position and against a stop pin 263 which is carried by the insulating material member 258. When the pick-up arm is in playing relation to a record,

the member 235 assumes an inclined position between its pivot and the serrated edge of the member 260.

In the event that operation of the magazine is to be manually stopped, the pick-up arm 221 is raised slightly and given a backward swinging movement so as to cause the lower edge of the hinged element 235 to engage one of the serrations of the member 266. The member 235 will swing through a vertical position and thereby depress the engaged portion of the member 260 to cause the tail portion 264 of said member to engage the member 249. An electric circuit is thereby established through the members 232, 235, 260, 264, 249, and the spring 259, whereby the magnet |46 will be energized and the record transferring mechanism set into operation even though the record has not been completely played. Accidental backward movement of the pick-up arm will, of course, also effect stoppage of the mechanism by reason of the engagement of the hinged member 235 with the serrated edge of the member 260, as above explained.

During such return movement of the played record, the cams 246 and 244 are, of course, rotated in a. counterclockwise direction as viewed in Figs. 15 and 21 and the cam 244 acts on the roller 243 to swing the lever 23| upwardly in a counterclockwise direction about its pivot 236. By reason of the mounting of the pick-up arm 221 on the lever 23|, the said pick-up arm is also swung upwardly away from the turntable. The cam 246 also acts on the ball end 241 of the lever 246 to swing the arm 221 about its vertical pivot 230 from innermost to its outermost position wherein it is again held by engagement of the tongue 24| in the slot 240.

As previously explained, when the magnet |46 is energized, the bar |39 is moved forwardly by the spring |4|. For restoring the arm |39 to its initial position, the cam 245 is provided with a laterally projecting pin 253 which is adapted to engage the upwardly projecting end of a dog 254 which is pivoted as indicated at 255 on the bar |39. A spring 256 normally holds the dog 254 in upwardly extending position and against a stop pin 251 which is also carried by the bar |39.

When the cam 245 rotates in clockwise direction to place' the pick-up in operative engagement with a record, the pin 253 engages the front edge of the dog 254 and, as an incident tothe last portion of rotation of the cam 245, moves the bar |39 rearwardly against the tension of the spring |4|. Upon counterclockwise rotation of the cam 245, the pin 253 engages the rear edge of the dog 254 and merely causes the dog to swing on its pivot 255 against the tensionof the spring 256 without imparting any movement to the bar |39.

A spring 262 normally .'perationofthe mechanism The operation of the various parts of the described mechanism has been explained in connection with the description of such parts, but to facilitate understanding of the complete cycle of operation, the following brief explanation is madez The initial or starting position of the phonograph mechanism is illustrated in Figs. 2, 3, 4 and 21. The magazine may be considered in any predetermined position wherein a record is aligned with the transfer jaws 49 for the first playing of either side thereof.

When the mechanism is provided with a coin control device and a proper coininserted, the

' electric circuit will be through the coin control switch C which is controlled by the lever |55, and through the contacts 254 and |51 to the motor (see wiring diagram, Fig. 24).

When the motor 23 is thus energized, power is transmitted through the shaft to the countershaft and through the gears ||4 and ||5 to the pinion ||1, which in turn eects forward or clockwise rotation of the cam shaft 55. The cams 33 then become operative'to force the record gripping jaws 45 into overlapping position relative to a marginal portion of the record, substantially as shown in Fig. 5. 'I'he cam 39 thereupon forces the cam-headed pin 51 outwardly to squeeze the record gripping jaws together to clamp the record therebetween. substantialLv as shown in Fig. 12.

During the above described movements, the lockingpin 15 has been held in locking engagement with the apertured part 23 (Fig. 3), but when the cam 33 arrives at the position in which the record is clamped between the jaws as in Fig. 12, the recess 5l in the disc 14 becomes aligned with the locking pin 15 and permits the latter to be retracted by the spring 15 so as to unlock the record transfer mechanism (see Fig. 12).

Continued forward rotation of the cam shaft 53 and its various cams then acts to swing the jaw carrier and record holding jaws about the cam shaft 35 as a pivot, the engagement of the locking pin 15 with the recess in the disc 14 con stituting a semi-positive driving connection between the record transferring mechanism and the cam shaft 55.

Forward and downward swinging movement of the record transferring mechanism continues until thecross bar element 34 of the jaw mount engages the frame element 55 (Fig. 13) to stop fur-v ther swinging movement 'of the transferring mechanism. The locking pin 15 is then forced out of the recess 85 inthe disc 14 and caused to enter the aperture 55 in the frame part 51 (Fig.A 14) while rotation of the cam shaft 55 and parts f connected thereto continues.

`tion as shown in Figs. 1, 9, 13 and 14. As soon as the jaws arrive at their horizontal position,

the continued rotation of the cam 5s permits the spring 13 to retract the cam headed pin 5,1

to thereby permit the jaws to separate and release the record which is then resting on the turntable (see Figs. 13 and 14). The cams 53 are so shaped, however, that the jaws 48 remain in their overlapping position relative to the marginal portion of the record.

The turntable is continuously rotated through the described connections so that as soon as the record is released, by the jaws, the record be- .gins to rotate with the turntable.

During the forward and downward movement ofthe record carrying mechanism, the pick-up and pick-up arm are also swung from initial upwardly, extending position as shown in Fig. 5 to playing position as in Figs. 1 and 15.

When the record has been delivered to thel turntable and the pick-up placed in operative engagement with the record, the pin |32 of the disc swings the bell crank |34 to eect adjustment of the shaft ||5 towards the right (in Fig. 7), with the result that the driving connection between the gears ||4 and I|5 is broken. Inl other words, the gears ||5 and ||5 are in a neutral position relative to the driving gear |4. Hence, rotation of the cam shaft 55 stops.

When the playing of a record has been completed the electro-magnet |45 is energized, the circuit being then through the spring contacts 223 and 224, through vthe contact element 25|, 245, 234, 232, and through the magnet |45 (see the wiring diagram. Fig. 24). As above explained, the insulating material element 222 carried by the bar |35 serves to break the circuit just described almost immediately after it is completed so that the magnet |45 does not remain energized for more than a very brief period. Hence, the use of excessive current and the danger-of .burning out the magnet is eliminated.

When the bar |39 moves forwardly suiilciently to remove the stop element |33 from the path of movement of the shaft Ill, the stored-up power in the spring |22 completes the movement of the shaft ||8 to the right (in Figs. 7, 19 and 20).l The ilnal or extreme right-hand position of the shaft I|3 is shown in Fig. 20 and in this position, the gears ||5 and ||4 are engaged, with the result that the cam shaft 55 is rotated in the reverse or counterclockwise direction to return the record from the turntable to the magaZne;

The clamping action of the jaws on the record is first effected by engagement of the cam 55 with the inner end of the pin 51, whereupon the locking pin 15 is permitted to dop into the notch 50 of the disc 14, therebyunlocking the transfer mechanism from the frame part 31. Then the record transferring jaws swing upwardly, first engaging the turning stud or pin which had caused initial turning of the jaws from vertical to horizontal position. The jaws are thus restored to vertical position and the record transferred to its original place in the magazine. The cams 55 and 35 continue to rotate until'the jaws release the record and withdraw from overlapping position relative to the marginal portion of the record and resume their initial or starting position as shown in Fig 2.

-Near the end of the return movement, the

cam |51 actuates the, coin control switch lto break the motor circuit, thereby to stop the rearward rotation of the cam shaft 55.-

When another coin is deposited, or in the event that the coin control mechanism is eliminated and the mechanism operates continuously and automatically, the cam shaft 55 would continue its rotation for a slightly additional amoimt until the pin |3| actuates the bell crank |34 to return the' shaft ||3 to its initial position wherein the gear IIS meshes with the driving gear iii. Thereupon, the cam shaft It would again be driven in forward or clockwise direction.

Just prior to breaking of the circuit through the coin control switch and just prior to the time the pin i3! acts on the bell crank l, the cam IBI actuates the pawl lever Ill and pawl |11 to advance the ratchet |16 and magazine feed cam |63. Inasmuch as the cam seats i are of such length that it takes two steps of movement of the cam to shift the record magazine, the ilrst step of turning` movement imparted to the cam will not shift the magazine. However, the cam disc i is advanced one step in unison with the cam lil andit acts on the end |02 of the rod 98 to shift the turning fork 92 so as to align `the other turning pin or stud 93 or S4 with the top of the nange which was not engaged'in the .previous .record transferring operation. Hence, when the cams Il and "and 14 again cause the jaws to grip the same record and to transfer it to the turntable, the jaws and record will be turned in the reverse direction about the axis of the stein Si to thereby place the record on theturntable with Vits oppositeface up. The pick-up device is then again brought into operative engagement with the record and the same playing and record return;

movements repeated in due course.

The next operation of the magazine shifting cam |63 will, of course, effect outward movement of the roller |80 and thus impart feed movement to the magazine to align a new record with the jaws. Thereafter. the same record feeding and turning movements are effected.

It will be observed that the operations of the mechanism described are all eifected from a single cam shaft It, whereby the mechanism may be made comparatively small and compact, with A the additional advantage that the weight of the mechanism is maintained at a minimum.

. By reference to the wiring diagram, Fig. 24, it will be seen that there are, in effect, two separate electric circuits, one for controlling the operation of the electric motor. and the other for energizing the electromagnet I". These circuits are adequately controlled so as to'prev'ent im- I proper operation of the mechanism.

I am aware that the described mechanism may be changed in many respects without departing from the spirit of my invention. the scope of which should be determinedby reference to the following claims, the same being construed as broadly as possible consistent with the state of 'the art.
